Many of the GDC tapes are BetacamSP format and subject to problems involving the magnetic signal. While the audio is not quite as noticeable, the video image can show a fluttery, milky overlay to the original recording. By applying a flicker reduction filter via Virtualdub, the time cost in re-rendering the material is made up for by the increase in quality. This demonstration shows a single range of tape before and after the filtering.
